Synthesis and photocatalytic mechanism of visible-light-driven AgBr/g-C3N4 composite

g-C3N4 is a well-known visible-light-active photocatalyst for the degradation of environmental pollutants. However, its photocatalytic activity is restricted by the small specific surface area and the e−/h+ recombination rate. In order to improve the photocatalytic performance of g-C3N4, AgBr/g-C3N4 composite photocatalyst has been designed. The as-prepared AgBr/g-C3N4 was characterized by X-ray diffraction (XRD), field emission scanning...
